SHIF'IER CLAMPING DEICE.

Application filed April l13,

that tags or `other means of identificationy can be applied by 'a sewingmachine to each sheet without disarranging the pile.

I will now proceed to describemy inv`ention in detail, the Vnovelfeatures of which I will point out in the appended claims, xref crencebeing had to th accompanying draw# ings, wherein Fig. V1 illustratesa'face view of my improved clainp, a portion ofa pile of stacked sheetsbeing illustrated asy held thereby; Fig. 2 is a sectional side view7 thesection being taken'on a line 2 2 in Fig. 1;

rlhe clamping device which I have designed is intended mainly for use inconnection with a pile` of superimposed layers of cloth to whichidentification tags or other labels are to be applied by sewingmachines. The layers are piledso that the edges aline, or at Vleast oneedge. Each layer kcomprising the pile is turned down afterthe tag orlabel has been applied thereto in order that the next succeedingupperlayer can have l tation upon the part of said post 11.

Serial No. 552,169.

applied thereto its label, the same being applied by hand or machine.

As herein embodied, my invention comprised of a clamping post 11 carriedby a slide-rest 12 movable longitudinallyl of a rail 13 secured, at eachend, by clamping jaws 14 and 15, the jaw-member 15 being adjustable bymeans of'a lead-screw 16, to a suitable support 17, be it a. bench orthe table for a sewing machineor stamping device. At its upper end, post11 carries a beam 18 which is pivotally connect-edA to post 11 by apivot pin or screw`19. The

'beam 1S supports a resilient clip or arm 20 which `is pivotally securedto beam 18 by a pin or screw 21. The rest 12 carries an arm extendingover the face of support 17,

ing provided to facilitate the movement of the clamping head as a wholeover the surl face of the support.

The post 11 carries a plurality of spaced apart projections 24 designedto be acted upon by an eccentrically mounted disk 25 carrying an arm 26.The disk 25 carries a fla-nge 27 to engage the projections 24. The disk25 vis pivotally connectedby a screw 28 to bracket 29 carried by theslide rest 12, as can be seen in Fig. 3. The flange 27 on disk 25 is cutaway at 30 and 31 (Fig. et) to permit the projections 211 to passthrough when the pressure device or disk 25 is moved ,post 11-isprovided with a slot 32 through which rail 13 passes. thereby preventingroi The clamping jaw 14- and arm 22 are preferably .made integral withtheir 'respective parts Fig. 9 isa fragmentary plan view `of the" whichpass through slot 341 in the plate portion 35 of jaw 15. The lead screwis rotatably secured, at its upper end, to a lug 36 carried by rail 13.When screw 16 is manipulated, jaw 15 will be moved up or down toaccommodate the thickness of the Support 17.

The clamping head, indicated generally lby A, in Fig. 2, is made movablelongitudinally of its rail in order that said head can be moved up to asewing machine (not shown). should same be carried by support 1". Thegoods to be marked or labeled are placed between beam 18 and arm 20, thedisk 25 being positioned, as indicated in Fig. 4

after which the post l1V will be forced down wardly to cause arm 20 tofirmly engage the pile of superimposed layers of cloth, indicated by B,whereuponfarm Q6 will be moved to the rightor left, causing flange 27 toengage an adjacent projection or lug 2i, thereby imposing pressure uponthe post and also locking,V the post in depressed position.

To Ha )olv identification marks to the layers, the pile will b e liftedup er folded back, leavingr ,the bottom layer flat. The clamp l now bemoved toward die sewing machine indicated by C Figa l() andthe lowermostlayer' placed upon the plate 3i' and .se-wed after ,vhicli the clampingderice will be moved back, pulling the layer to which the label ,or thelike has been serve/l.V

When the clamping' `device drawn back, the eiul of the loweruros; layerwill drop thrlougli an ope1i,ingr 3S' insupport 17. y The neX`ty upperlayer will now he pufllcoff the rol-led4 back layers and :theclamping;device moved up tothe machine, hereinbelfore explaiined.` Thesecond lay/'er wil-l be dropped through opening 38 after the label hasbeen applied thereto.y yThis operation will repeat until .all theAlayers-have sbeen labeled. The clip 2O serves :to hold-.the rolle-:glback layers indicated in Il`ig'.A 10,
